EJEGTING MECHANISIVI FOR VfIRE-SCRAP-REELING MACHINES.

Lismore.

Application tiled December 1, 1913.

To all' whom it muy concern Be it known that I, GEORGE W. STALEY, citizen of the United States, residing at Johnstown, in the county of Cambria and State of Pennsylvania, have invented certain new and useful improvement-s in Ejecting Mechanism for lfVire-Scrap-Reeling Machines, of which the following is a specilication.

My invention relates to machines for reeling wire and particularly to machines designed for the purpose of reeling wire scrap, these machines being known as Cobble ballers. l-leretofore in machines of this character after the wire scrap has been wound up in the form of a cylinder, the spindle upon which it is wound is removed and the cylinder of wire scrap allowed to drop' upon the base of the machine. rl`his pull or roll of wire scrap is very heavy and heretofore in machines of this type a number of men have been employed to roll and push the bundle of scrap wire olf the base.

The primary object of my invention is the provision of power-operated means for the purpose of shifting the roll off the base of the machine and thus permit the reeling operation to be suspended for a relatively short time.

A further object of the invention is to provide power-actuated means for this purpose of very simple character and readily operated.

A. further object is the provision in a machine of this character, of a power-actuated plunger or pusher designed to be operatively enga ged with the power shaft and the provision in connection therewith of automatic means for throwing olf the power or disengaging the plunger from the power shaft when the plunger or pusher has arrived at one or the other of its extremities of movement.

Other objects will appear in the course of the following description. i

My invention is illustrated in the accompanying drawings, wherein Figure l is a plan view of a machine constructed in accordance with my invention. Fig. 2 is a side elevation thereof. Fig. 3 is a detail view of the clutch mechanism between the plunger and the power-shaft.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.

`While I do not wish to be limited to any specific type of bundling or scrap reeling mechanism, I have illustrated a form ordinarily in use to-day, this machine comprising a base 2, the laterally spaced standards 3, the spindle 4 upon which the scrap wire is reeled, and the roll 5 which constitutes a weight rolling on and bearing down on the bundle of wire rolled upon the spindle 4. The spindle 4 is tapering, as shown in Fig. 1, and is laterally removable from its bearings in the standards 3. The upper end of each standard 3 is vertically slotted as at 6 to receive the trunnions 7 of the roll 5. 1n this type of machine the scrap wire is reeled up upon the spindle 4, power' of course being applied to this spindle in any suitable manner, and the roll 5 yieldingly bears upon this reel of scrap wire. As the reel or bundle of scrap wire grows larger in diameter the roll 5 will rise but it will always bear upon this reel or bundle of wire so as to compress it as much as possible. When the reel or bundle of wire has become as large in diameter as is permitted by the roll 5, the spindle 4 is withdrawn and the reel or bundle of wire drops upon the base 2. Heretofore this reel of wire has been shifted from the base by two or three men using crow-bars for the purpose and it is obvious that during this removal of the bundle the machine cannot be operated. Not only is time lost but as before remarked, the services of two or three men are required for the purpose.

lln order to carry out the purpose of my invention, I provide power-operated means for shifting the bundle A of wire from the base. rIhis power-operated means consists of a plunger or pusher designated 8. This rests at its middle upon a roller 9 mounted in a suitable supporting base 10. The forward end of the plunger 8 is formed with a laterally expanded and downwardly eX- tending head 11 braced by flanges from the plunger bar 8. The upper face of the bar 8 is formed with rack teeth l2 for engagement with a gear-wheel 13. This gear-wheel is mounted loosely upon a shaft 14 supported in suitable bearings in the base 10. This shaft 14 is a power shaft actuated from a power source. The face of the gear wheel 13 is formed with clutch-teeth 15 and slidably mounted upon the shaft 14 isa clutch member 16 which is splined upon the shaft to rotate therewith and has free sliding movement into or out of engagement with the clutch-face of the gear-wheel 13. The clutch member 16 is shifted by'means of a handle 17 or shipper rod.

The rear end of theraclr bar or plunger' 8 is supported by means of a support 18 having upwardly extending guide arms or flanges 19 between which the bar 8 slides. The forward end of the bar 8 is supported yby means of a supporting barQO mounted on braclre'tsor legs'21f. By referring more particularlyto Fig. 2 of the drawings it will be noted that this supporting'bar 2O is above the lowest point of the expanded head- 11 of the plunger and, therefore,it will serve as a stopfto-limit the outward or receding movement o f the yplunger andf prevent it being carriedv so far'froin the supporting'table that time will be lost inbringing the plunger into engagement with* the-roll of wire when it is desired' toeject said roll".y I thusguard againstun'due movement of the rack vand plunger inasmuch asthe forwardI lateral lug '23 will engageithe movabley clutch member andfshift'fthe same"'fromitsvengageme'nt with the gear wheel 13' and the head of the plunger will then engage the supporting bar 21 so that no unnecessary movementof the plunger ywill occur.

For the purpose of throwing the clutch out-ofl mesh in case the yoperator neglectsto throw it out himself when the plunger has shifted to either eXtreme of itsfmoveinent, I provide laterally projecting lugs 22-and 23 formed upon the raclr-bar, these lugs having inclined facesQA' on their inner edges adapted'to engage with the clutch-'member 1.6. These clutch shiftinglugsQQ and 23 are disposed respectively at opposite'endsofthe plunger bar Sadjacent' the ends of the rack 12 lso that when the plunger-bar is moving forward? and thefinclined face of the lug' comes into contact with the'member 16 it will shift it outward, thus unclutching the gear wheel 13 from the shaft 154C andv softhat when on the otherfhand the plungerf'bar-"S isy moved rearward` and the lug 231en'gages with the clutch member 16, the gear wheel 1'3lwill be-unclutched from the shaft'lliand the power thrown oil".4 This'will' automatically pre'vent' any breakage of' the'mechanis'm due* to the carelessness of' the/workmen.

It isy obvious'l that with: 'my' invention vthe bundle of wire when it is reeled up may be readily and quickly pushed off of the base 2 and the machine readily placed in condition for rewinding a fresh bundlelof wire. It is also seen that with this arrangement only one man is needed to attend to the machine and that considerable economy in time is secured. The shaftv 14 will of course be operated by any suitable power, and means of course will be provided for rotating the shaft in onedirection or the other in order to shift the plunger bar 8 inward or to retract the plunger bar.

While I have illustrated what I believe to be the best forni ofmy invention, I do not wish to be limited thereto, as it is obvious t-hat many changes might be made without departing from the spirit of the invention'.

Having thus described the invention 'what is claimed as new is :h

In an ejecting mechanism for wire reeling machines, the combination of a table, a supporting bar mounted upon said table above the' surfacethe'reof, guides disposed in alinement at one side of the said supporting bar, a plunger mounted in said guides and resting upon said'supporting bar and provided at its end beyond saidbar and over the table with a laterally and downwardly expanded head adapted to impinge against the reel to be ejected-,a rack upon the upper side ofsaid plunger, a gear-wheel mounted in that guide nearer the table and meshing with said rack, a driving-shaft liourna-led upon said guide and extending laterally therefrom Aand fitting loosely with-in saidlge'ar wheehfa'manually movable clutch member mountedupon the said shaft and adaptedto engage said gear wheel, and laterally projecting lugs on the 4-sid'ev of the plunger at opposite sides'of the gear wheel having" inclined faces adapted to engage said'v clutch member and shift the same out of engagement with the gear'wheel to arrest the movement r of the plunger-at'either'endof its stroke,

InE testimony whereof Il affixr my signature in presence of two" witnesses.
